The speed of sound in steam is predictable if steam dryness is known. [45] Also, the specific volume of steam for a given temperature decreases with decreasing dryness. [46] [39] Two examples of estimates of speed of sound in steam calculated from whistles blown under field conditions are 1,326 and 1,352 feet per second. [47]

These devices are whistles that do not radiate sound, but are still aerodynamic whistles. The upper figure on the right shows the basic arrangement of one version of the device. The circle on the left is the fluid source (air or liquid). A jet is formed that either goes into the upper or lower channel. The black lines are the feedback paths.
So, locomotive air horns were created that had a much higher, more musical note, tonally much more like a steam whistle. This is why most train horns have a unique sound, different from that of road going trucks, although many switch engines, which didn't see road service (service on the main lines), retained the deeper truck-like horns.
Robert Swanson founded Airchime Ltd., beginning by making custom steam whistles in his British Columbia home. He preferred the sound of steam whistles over the single-chime horns made by Leslie and Westinghouse Air Brake Company.

Steam whistles were also used as a warning device if a supply of steam was present, such as a sawmill or factory. These were common before fire sirens became widely available, particularly in the former Soviet Union. Fire horns, large compressed air horns, also were and still are used as an alternative to a fire siren.
